BX Elevator general description
BX Elevator limitations
The BX Elevator is designed to be used as an elevator for lifting tubular goods in the gas and oil
well drilling environment, and must not be used for any other purpose.
Major components
The BX elevator is a hydraulic operated double door elevator, which is equipped with replaceable
bushings to handle various styles and sizes of tubular. The elevator will automatically close when
the pipe hits the body bushing. Opening of the elevator is remote controlled. The BX-elevator
has a vertically spring loaded bushing in the right hand door, which, pushed downwards under
load, will activate a mechanical latch lock to prevent accidental opening of the elevator while
lifting load.By detecting the return signal-pressure (XP-line) from the elevator it is determined
that the elevator is properly closed and latched.
The elevator is contains an easy removable cylinder pack, manifold block and bushing set.


The combination of elevator and rotator is suitable for 750 and 1000 tons NOV links.

In day to day practice the elevator is used to run drill pipe, casing and drill collars. Under
no circumstances should the loads applied to the elevator exceed the rated load on the
bushings.
Latch valve
In order to prevent a false “BX Closed” signal due to a combination of poor maintenance and
wear, the BX elevator is equipped with a latch valve. Once the latch is closed a pilot port opens
at the latch cylinder. Pilot signals from door and latch cylinder have to be present simultaneously
to get an elevator closed signal (XP-signal). The latch valve is connected in series with the
existing door and latch signals. Pilot signals from door cylinder, latch cylinder and latch valve all
have to be present simultaneously to get an elevator closed signal (XP-signal).
Design safety factor.
The design-safety factor and design verification of the elevators is in accordance with
requirements of API specification 8C.
During manufacturing the elevator is proof load tested to 1.5 times the rated load.
Limited warranty
The warranty will be void if the BX Elevator or parts were either:

unauthorized modified, repaired or serviced

replacement parts not manufactured by NOV were utilized

not properly stored or maintained

1) In this example: BX4-75 with 2.875” tube.
Minimum yield on elevator bushing: 110,000 Psi
Max. load in bushing: 750 sTons
Area:
π ( D²- d²) = π (3,400² - 3.079²) = 1.633 sq. inch

4
Allowable force:
Area x Yield = Lbs
1.633 x 110,000 = 179,630 Lbs
Allowable pipe load (static):
179,630 Lbs = 89.815 sTons
2000
In this example, the rating is determined by the bushing due
to yield as a result of the small shoulder surface of 1.633
sq.inch. Verify with pipe manufacturer!

2) In this example: BX4-75 with 3.1/2” drill pipe.
Minimum yield on elevator bushing: 110,000 Psi
Max. load in bushing: 500 sTons
Area:
π ( D²- d²) = π (5,000² - 3.875²) = 7.842 sq. inch

Allowable force:
Area x Yield = Lbs
7.842 x 110,000 = 862,620 Lbs
Allowable pipe load (static):
862,620 Lbs = 431.31 sTons
2000
See also the graph.
In this example, the rating is determined by the tubular as the
bushing will h500 sTons. However, a pipe with an OD of 3.1/
2” will probably not be able to ha load of 431.31 sTons. Verify
with pipe manufacturer!

Lubrication & Maintenance
NOTE: The owner and user together with the manufacturer should jointly develop and
update inspection, maintenance, repair and remanufacture procedures consistent with
equipment application, loading, work environment, usage and operational conditions.
These factors may change as a result of new technology, product improvements or
fundamental changes in service conditions.
NOV recommends using the Periodic inspection and maintenance Categories and
Frequencies as mentioned in API RP8B Table 1. Detailed instructions for maintenance
according to API RP8B Table 1 are outlined in this chapter.
Safety
WARNING: It is not allowed to weld on elevators. Please contact an authorized NOV
repair facility.

Greasing the inserts and insert slots.
NOTE: To reduce the chance of inserts seizing in the insert slots, NOV recommends to
remove the inserts after each job, coat the insert slot with light machine oil, EP-2 grease or
any other fluid that does not affect the friction coefficient with string weight compared to a
none coated insert slot.
WARNING: No grease or pipe dope should be used for lubricating the inserts and
insert slots as this will reduce the friction coefficient resulting in higher loads on
the slip toe and thus higher stress.

3: Lubrication and maintenance
Maintenance
WARNING: Ensure that all hydraulic lines are
disconnected before ANY work is performed on the
elevator. It’s not always sufficient to isolate the
hydraulic lines by using a ball valve, as the hoses
might function as an accumulator, which could
generate movement of the elevator. The ball-valve is
installed to ease connecting and disconnecting the
QD with pressure still on the line and for
disconnecting the elevator from the power source.

Maintenance procedures
API recommended practice according to API RP 8B
NOTE: NOV recommends maintenance acc. to API RP8B
Recommended inspections
The user/owner of the equipment should develop schedules of inspection based on experience,
the manufacturer's recommendations, and one or more of the following factors:
environment; load cycles; regulatory requirements; operating time; testing; repairs;
remanufacture.
Alternatively, NOV recommends using the Periodic inspection and maintenance Categories and
Frequencies as mentioned in API RP8B Table 1. Long-term planning shall be adjusted in order
not to interfere unnecessarily with the running operations.
5 Inspection and maintenance
5.1 General
5.1.1 Criteria
Inspection and maintenance are closely linked. Inspection and maintenance actions may be
initiated based on, but not limited to, one or more of the following criteria: specific time intervals;
measurable wear limits; load cycle accumulation; non-performance of equipment; environment;
experience (history); regulatory requirements.
5.1.2 Safety considerations Operators shall review safety considerations applicable to the site
where the maintenance activity is performed.
5.2 Maintenance
5.2.1 General
Maintenance of equipment consists of actions such as adjustments, cleaning, lubrication, and
replacement of expendable parts. The complexity of these activities and the safety risks involved
shall be considered in the assignment of appropriate resources such as facilities, equipment and
qualified personnel.
5.2.2 Procedures
In addition to the procedures developed in accordance with 4.1, the manufacturer should define
any special tools, materials, measuring and inspection equipment, and personnel qualifications
necessary to perform the maintenance. The manufacturer should also specify those procedures
that should be performed solely by the manufacturer, either within the manufacturer's facility or
within another approved facility.
5.3 Inspection
5.3.1. General
The existence of cracks can indicate severe deterioration and impending failure. Their detection,
identification and evaluation require accurate inspection methods. Prompt attention is then
required either to remove the equipment from service immediately or to provide appropriate
service and/or repair. Caution shall be exercised to take into account the increased susceptibility
to brittle fracture of many steels when operating at low temperatures. If any manufacturing
defects are discovered, they should be reported to the manufacturer or supplier.

5.3.2
Inspection categories
5.3.2.1 General The objective of these inspections is to detect service defects and possible
hidden manufacturing defects. Inspection results shall be reported on equipment files and
drawings.
Category I.
This category involves observing the equipment during operation for indications of inadequate
performance. When in use, equipment shall be visually inspected on a daily basis for cracks,
loose fits or connections, elongation of parts, and other signs of wear, corrosion or overloading.
Any equipment found to show cracks, excessive wear, etc., shall be removed from service for
further examination. The equipment shall be visually inspected by a person knowledgeable in
that equipment and its function.
Category II.
This is Category I inspection plus further inspection for corrosion, deformation, loose or missing
components, deterioration, proper lubrication, visible external cracks, and adjustment.
Category III
This is Category II inspection plus further inspection, which should include NOT of critical areas
and may involve some disassembly to access specific components and to identify wear that
exceeds the manufacturer's allowable tolerances.
Category IV
This is Category III inspection plus further inspection for which the equipment is disassembled to
the extent necessary to conduct NDT of all primary-load-carrying components as defined by
manufacturer. Equipment shall be:


disassembled in a suitably-equipped facility to the extent necessary to permit full
inspection of all primary-load-carrying components and other components that are critical
to the equipment;
inspected for excessive wear, cracks, flaws and deformations.
Corrections shall be made in accordance with the manufacturer's recommendations.
Prior to Category III and Category IV inspections, all foreign material such as dirt, paint, grease,
oil, scale, etc. shall be removed from the concerned parts by a suitable method (e.g. paintstripping, steam-cleaning, grit-blasting).
5.3.3 Frequency
5.3.3.1 Periodic inspection The user/owner of the equipment should develop schedules of
inspection based on experience, the manufacturer's recommendations, and one or more of the
following factors:
environment; load cycles; regulatory requirements; operating time; testing; repairs;
remanufacture.
As an alternative, the user/owner may use Table 1 guidelines. Long-term planning shall be
adjusted in order not to interfere unnecessarily with the running operations.
5.3.3.2 Non-periodic inspection A complete, on-job, shut-down inspection equivalent to the
periodical Category III or Category IV (for the concerned equipment) should be made before (if
anticipated) and after critical jobs (e.g., running heavy casing strings, jarring, pulling on stuck
pipes and/or operating at extreme low temperatures).

Tool joint wear data drill-pipe
Procedure
1. Determine the center bore diameter of the bushing in inches (size X)
2. The maximum wear on the diameter of the center bore: Nominal size + 0.25 inch
3. In the table, follow the line corresponding with the rating of the elevator (in short
tons)
4. On the left hand side, read out the minimum required tool joint diameter (Y) in
inches that can be handled safely with the elevator.
5. As soon as the tool joint diameter falls below the corresponding rating line, the
bushing or the pipe must be changed.
Tool joint Y
X
Example: 5 1/2” Drill pipe bushing, rated 350 Tons
Procedure
1. Actual center bore (X) is 5 13/16. Follow the vertical line up until the “350 Tons” line.
2. Follow the line horizontally.
3. Read out minimum required tool joint diameter (Y) = “6 ¾“

NOTE: Only a Varco BJ authorized repair facility is
allowed to remanufacture HT BX Elevators which have
indications outside the acceptance criteria.
Tests
Load test
The BX Elevators are load tested after manufacture or repair to 1.5 times their rating.
WARNING: BX Elevators which have experienced wear or
are found to have cracks must be replaced or repaired by a
Varco BJ authorized repair facility.
WARNING: Only original Varco BJ parts must be used. BX
Elevators are produced from cast alloy heat treated steel
and must not be welded in the field. Improper welding can
cause cracks and brittleness in heat-affected areas which
can result in dramatic weakening of the part and possible
failure. Repairs involving welding and/or machining should
be performed only by an Varco BJ authorized repair facility.
Using a BX Elevator that has been improperly welded or
repaired is dangerous.
Cylinder seal test
Checking for the condition of the seals in the BX-cylinders is to be carried out once a year.
Procedure

Remove cylinders from elevator

Try to remove any remaining fluid from the cylinders by stroking them in and out manually
a few times

Plug off the Xp (barrel) port.

Put system pressure (2,500 psi) on the rod side of the cylinder. CAUTION: Ensure cylinder
cannot spray any leaking oil via the open port into air causing damage or injury to anyone.

On the piston side of the cylinder appr. 1 cubic centimeter/min (about a teaspoon) is
allowed to leak.

If there is considerable more leakage, replace seals.

Installation and commissioning
General procedure
A range of control manifolds and hook up kits to control the elevator or elevator/rotator
combination are available. The control manifolds also protect the elevator and rotator against
overload.
Installation
WARNING: Make sure that all hydraulic lines are
disconnected before ANY work is performed on the
elevator. When the lines are connected the elevator
doors will close when the bushing / trigger
mechanism is hit which can cause serious injury to
personnel.It’s not always sufficient to isolate the
hydraulic lines by using a ball valve, since the hoses
might function as an accumulator, which could
generate movement of the elevator
System requirements check
Procedure
Initial checks system requirements
Check whether all tubing and hoses that connect the BX-elevators to the TDS-power
unit or rig main ring have a minimum of ½” nominal diameter.
Check maximum system-oil temperature: Maximum 180ºF (82ºC).
Check that the maximum back-pressure on the return line does not exceed 250 Psi.
Check availability of correct control panel & control functions
Check hoses on damage and free movement.
Check the minimum – maximum pressure: 2000 – 2500 Psi (13,790 - 17,237 KPa) and
5 Gpm (19 l.min)
Check the pressure on the XP-line: When the elevator is commanded to open, the
pressure should be about 250 Psi (1,723 KPa) higher than in the P-line.

Operations
Intended usage
The BX-elevator is designed to RUN IN HOLE (RIH) and to PULL OUT OF HOLE (POOH) of
various drill-stem tubulars and casing.
WARNING: Ensure that all hydraulic lines are
disconnected before ANY work is performed on the
elevator. It’s not always sufficient to isolate the
hydraulic lines by using a ball valve, as the hoses
might function as an accumulator, which could
generate movement of the elevator. The ball-valve is
installed to ease connecting and disconnecting the
QD with pressure still on the line and for
disconnecting the elevator from the power source.
Hydraulic filters
Depending on the quality of the hydraulic fluids on the rig it is important to check the condition of
the inline-filters on a regular basis. The filters are designed to stand for at least 1-year service in
conditions as required in this manual (see chapter 2). However, rig conditions may differ from
these required conditions, or change by contamination, incidents, repairs etc.
Depending on the actual conditions it is important to conduct regular checks on the filters in the
manifold block. For this reason the manifold block, the hoses and couplings need to be checked
and cleaned thoroughly. It is advised to conduct the check at least after 1 month of service, after
6 months service and after one year of service. Depending on the results of the checks the
interval between checks can be increased or decreased.
Filter in manifold block
Procedure
1. XP-line filter on the side (p/n 979796-25-S)
2. Check filters.
3. Clean filters when needed (rinse with a solvent)
Filter set: Spring (not shown) (p/n 980252) and Cartridge (p/n 979796-25-S)

Operations
WARNING: Never exceed the load rating of the
elevator, bushings and pipe at any given time in any
situation.
WARNING: The Driller should be checking the latch
indication is on and off every time the elevator is
latched and unlatched. The frequency of checking for
proper functioning of the latch should be at least
daily and at the beginning of every trip.
Procedure
1. Check that the elevator, pipe/lifting tool, links and link adapter are all properly loaded and
aligned to prevent unequal loading of any of these parts. Especially in case of increasing
loads this may become critical, when the load is ditributed in an uneven way, the stress
pattern in the elevator may change. This might affect the load rating of the elevator.
2. Ensure the latch feedback indication is on and off everytime the driller latches or unlatches
the elevator. This test should be carried out at least daily and at the beginning of every trip.
3. Never attemp to hoist a pipe without having received a positive signal “ elevator closed”.
4. Never give the command “open elevator” while there is still load suspended in the elevator.
5. Never give the command “ open slips” while there is still load suspended in the slips.
6. Use preferably a system, interlocking the BX-elevator with the Slips in the rotary in order to
prevent the slips to open when the elevator is open and vice versa.
7. Releasing a load from the elevator into the Slips.
a. Ensure the slips in the rotary are set. Verify the presence op “Slips Set” signal
b.
Lower the elevator. Observe hook load decrease an ensure load is transferred to slips
completely.
c.
Slightly lower hook (2 inch max) in order to release latch lock pin from elevator
d. Command elevator to open.
8. Picking up a load with the elevator.
a. Ensure elevator is commanded “armed to close”.
b.
Engage pipe with elevator.
c.
Elevator closes automatically.
d. Observe indication “elevator closed”.
e. Pick up weight of pipe. Observe hook load to ensure this happens.
9. Now open slips and handle the pipe.
10. The sum of the static and dynamic load in the elevator shall never exceed the lowest value
of:

the load rating of the elevator (verify load rating plate of elevator)

the load rating of the bushing (verify load rating stamped in bushing)
11. Verify pipe-load shoulder area for maximum contact stresses (verify according to
examples in chapter “ SPECIFICATION, Load ratings”).
12. Ensure the heave-compensating system, if applicable, is in good working order.

General note
NOTE: Use the proper torque for assembly parts.
Cartridges could be easily damaged by applying too much
torque. Apply 30-36 Ft Lbs (40 - 49 Nm) on cartridges
MAX.
Procedure
1. Assembly can be done by doing disassembly in reverse sequence.
2. Lock all parts as indicated on the assembly drawings.
3. Check the elevator according the Test Procedure (see TSEL-0048).
Cylinder adjustment
Procedure
After re-assembly of the elevator it might be necessary to adjust the cylinder package. When
cylinders are found to be out of adjustment, follow the procedures as described below. Check
first whether lock-nuts #944422-12 and SS lock-tabs #203268 are still in good condition. When
necessary replace these before doing the re-adjustment.
1. Hook-up the elevator to a Hydraulic Power-Unit using Varco BJ test kit #202539, or to its
HUK. Connect pressure gauges to the appropriate gauge ports for ’P’ and ‘XP’ on the
elevator manifold
2. Open the doors and close again, placing a 1 1/2” thck steel bar between the doors,
preventing the doors from fully closing. Connect (‘Tee-off”) a pressure gauge to the barrelport of the door cylinder.
3. NO signal (equal to ‘P’ pressure) may occur on the barrel-port gauge. Latch may NOT
start to close.
4.
When a signal (equal to ‘P’ pressure) out of the barrel-port is present (latch will start to
close) then turn the rod-clevis OUT. (Elongate the Cylinder)
5. Then remove the bolt or bar.
6. Power the doors to close fully.
7. When the doors are fully closed, (Tip of the doors MUST close against each other, NO
gap allowed.) , a signal (equal to ‘P’ pressure) out of the barrel-port MUST occur. (Latch
will start to close)
8. When NO signal occurs, turn the rod-end IN. (Shorten the Door-Cylinder)
9. With the elevator open, check whether doors are making contact with their Hard Stops
(see picture on next page). If not, turn rod-end clevis IN. (Shorten the Door cylinder.)
10. REPEAT this procedure until the proper barrel-port signals occur at the correct moment.

Latch Cylinder Adjustment.
Procedure
1. After Door cylinder adjustment is found to be OK, the latch cylinder must be adjusted
according the following procedure.
2. Power the elevator to close and latch
3. Check whether the closed latch is in contact with it’s hard stop on the left-hand door. Stop
is located on the inside (back) of the bottom latch strap. You may need to use markingpaint (Blue-Dye) to get a proper indication, as this hard stop is difficult to reach with a
feeler gauge. When latch does not contact hard-stop IN, turn rod-end clevis OUT.
(lengthen Cylinder)
4. In the condition described in item 2, the elevator closed signal on port ‘XP’ MUST be
present. (1,000 Psi / 6,895 KPa) When NO “elevator-closed-signal” (1,000 Psi / 6,895 KPa
on “XP”) Is present, turn rod-end clevis IN.(Shorten Cylinder)
5. Open the elevator and check whether latch is in contact with its Hard-stop for the open
position. If not turn the rod-end clevis IN. (Shorten Cylinder)
6. REPEAT these steps until OK.

7. As a final check, close the elevator with the mechanical latch lock pin in its UP position. In
this condition the latch will be prevented from closing fully by the Lock-pin. NO elevator
closed signal (1,000 Psi / 6,895 KPa) on line ‘XP’ may occur. This only applies for
elevators fitted with the so-called check-valve kit #203270-13.
8. When BOTH the door-cylinder and latch-cylinder are adjusted correctly, lock both rod ends
with their lock nut and SS lock-tabs. Do not to use the same folded part of the lock-tab
twice. Replace lock-tabs with cracks or other damage preventing proper locking.
9. Finally check the elevator with the test procedure (TSEL-0048) of this user manual.
WARNING: Ensure that all hydraulic lines are
disconnected before ANY work is performed on the
elevator.

WARNING: Ensure all hydraulic lines are
disconnected before any work is performed to the
elevator
NOTE: Use drawings #203270-1+13, “manifold assy” &
#203270-3+31 “hydraulic schematic”. The numbers
mentioned on the schematic #203270-3+31 correspond
with the numbers on drawing #203270-1 sheet 2.
Procedure
1. Before trouble shooting connect three pressure gauges to the standard gauge connectors
that are mounted on the BX manifold. The connectors can be found on dwg #203270-1
sheet 1 and dwg #203270-1 sheet 2:

“T”: Tank line, left-hand side of the manifold, bottom connector

“P”: Pressure line, right-hand side of manifold, top connector.

“XP” Signal pressure, left-hand side of the manifold, top connector.
2. Check that the hydraulic power supply is providing 2,000 Psi / 13,790 KPa minimum at the
elevator. The hydraulic power-unit pressure may need to be set higher at the power unit to
ensure that 2,000 Psi / 13,790 KPa (2,500psi / 17,236 KPa MAX) is available at the BXelevator.
3. Check hose-size to be ½” nominal diameter and flow being 5 GPM /19 l/min
4. Check Quick disconnects for dirt or malfunctioning, replace if necessary
5. Check that XP-line pressure (when elevator is commanded to open), is at least equal or
higher than P-line pressure.
6. Check the pressure in the return (Tank) line. Pressure may not exceed 250 Psi / 1,724
KPa.
Functioning hydraulics
When looking at schematic 203270-3, the elevator is open, door cylinder and latch cylinders are
in. Valve F is in the middle position.

7: Trouble shooting
Elevator Closing Sequence
When pipe is coming in the trigger activates valve L allowing pressure on line 5. Valve F then
shifts allowing pressure on line 7 which moves the door cylinder out. At the same time the retract
plunger is retracted inside the elevator bore, and is making room for the pipe coming in. The
elevator starts to close. When the door cylinder piston passes the signal port lines 10 is
pressurized piloting valve K open. This allows flow from line 7 to line 11 to start closing the latch
cylinder. When the latch cylinder piston passes the signal port line 12 is pressurized which
allows valve G to be piloted open. This allows flow from line 7 to line 4 and the float port. Valve D
reduces the system pressure to 1,000 Psi / 6,895 KPa which passes through valve C via XP to
the Pressure Switch mounted on the Top-Drive. This gives the driller the ‘elevator closed’
indication.
Elevator Opening Sequence.
When giving command to open by pressurizing XP with system pressure (must be greater than
the set value of 1,500 Psi / 10,340 KPa and equal or greater than P) , valve E opens and line 6 is
pressurized. This causes valve F to shift to its mid position. Line 7 is relieved of pressure and line
8 is pressurized. At the same time the retract plunger is relieved. Due to line 6 being pressurized
valve M is piloted open allowing flow from line 8 to line 14 causing the latch cylinder to move
inwards. As soon as the latch cylinder piston passes the signal port line 12 is pressurized which
pilots open valve H allowing flow from line 8 to line 9. At the same time the trigger is being
pushed back in the elevator bore. The door cylinder starts to move inwards. The elevator has
now unlatched and the doors are open. When the trigger finger no longer contacts the pipe the
cam valve shifts which depressurizes line 5. The command to open i.e. XP pressurized can now
be removed and the elevator is armed to close.
Test kit BX-elevator + power slip p/n 202539
This test kit can be used for trouble shooting and functional testing of the BX elevators and
rotators and PS 21/30 power slip. Its contents will allow in line pressure measurements to
determine the cause of a problem.
NOTE: Advised is to do the trouble shooting in the shop
instead of the drill floor because of the possible danger of
falling parts down the hole
The special hose assembly for the BX elevator will allow testing in the shop and only requires a
“pressure” and “return” line from the power unit. The way the kit is designed a “Xp” signal can be
generated by operating two ball valves.

Fig.1 shows the hose assembly for testing the BX elevator and rotator. Refer to drawing 202539
sh.1 (included in kit) that shows the assembly in a schematic. On the left side you see 3 lines
that must be connected to the elevator (pressure, return and signal Xp). On the right side there
are 2 lines that must be connected to the power unit (pressure and return). To the top and to the
right there is a PRV (pressure regulating valve) mounted. With this valve the pressure to the
elevator can be set to any desired value allowed by the HPU press .
Fig 1
Fig 2
Fig.2 shows most of the parts that are in the kit. Ref. Drawing 202539. It has spare pressure
gauges and hoses. The plate that contains 3 gauges can be used for checking the 3 pressures
on the elevator that are most important (pressure, return and XP signal). The hoses need to be
connected to the gauges and to the elevator standard connectors on the elevator manifold. On
the assembly drawing of the manifold the location of these connectors can be found. They can
also be recognized by the little cap and chain that covers the end of the connector. The plate has
an extra side plate on the back which makes it easy to clamp it onto the top flange at the back of
the elevator.

Lbs), An BX-3 elevator weights about 2,165 Lbs. / 975 kg, the heaviest bushing about 165 kg
(365 Lbs).
A rotator weights appr. 150 kg (330 Lbs).
How does a BX-elevator function?
The basic idea is to give the elevator a possibility to close ONLY when the trigger is hit by a pipe.
This will start the closing cycle. When the latch is properly closed the elevator will give a high
pressure signal generated by the supply line, through the signal line. This will generate the
signal “elevator closed and latched”. When the elevator starts lifting the spring powered bushing
will be pushed down and will power the mechanical latch lock. As long as weight is in the
elevator, the elevator CANNOT be opened.
Is it safe working on an elevator without disconnecting the
hoses?
The hoses could function as an accumulator and supply enough energy to start the closing cycle
when the trigger is hit (e.g. by the man working on the elevator). This could result in injury of
death. Hence it is required to disconnect hoses before starting any work on the BX.
What should I do when the elevator doesn’t functions well?
Start with conducting the possible causes as outlined in the chapter trouble shooting. When no
solutions at hand PLEASE contact an authorized Varco BJ repair facility. They will help you with
finding a solution. When you start adjusting the elevator without exactly knowing what you are
doing, you might increase the problem, even when the basic problem is a very simple one.
Why can’t I use parts from NON Varco BJ origin ?
All Varco BJ parts are tested and are traceable on vendor, material, strength etc. When using not
original parts one might use parts which are not strong enough for the purpose, which might
result in breaking of parts from the elevator.
I know how to operate an elevator. Do I need to read this
manual ?
It’s highly recommended to read this manual as the elevator, even though you feel you have
sufficient knowledge on how to operate one. It can be used to prevent problems and solve
problems when they occur. When following the maintenance advice you will have a reliable tool
with a long operational life.
Why can’t I use tool joint compound/pipe-dope as a lubricant ?
Tool joint compound is a sealant to prevent fluids from escaping out off the drill-pipe. This means
it is a sticky compound with basically the opposite result as required: It sticks parts, but doesn’t
make parts break loose easily (except from tool joints).

Storage, transport & scrapping.
Storage
When the elevator is not being used for a longer period then 3 days the following steps should be
carried out:

Remove the bushings.

Clean elevator and bushings.

Grease elevator and bushings as described in checklist lubrication.

Place elevator in closed position.

Grease all blank parts.

Use an extreme pressure, multi-purpose, lithium based grease of No. 1 or No. 2
consistency and multi grade motor oil.

Grease trigger finger-shaft.

Clean and cap hydraulic Quick Disconnect Couplings.

Recommended rust preventative (slushing compound) for bare metal surfaces: Kendall
Grade 5(GE-D6C6A1) or equivalent.
Transport

Lift the BX-elevator by the lifting ears only

The best way of transporting the BX-elevator is in its original crate. Use oiled paper and
seal the box with plastic from leaking when stored outside. Secure the top safely.
Scrapping
www.nov.com

The tool contains hydraulic fluids, grease, aluminum, steel, rubbers, plastic and several
assembled components from undefined consistency or mixtures. The tool can be
contaminated with mud.

When the tool is taken out of permanent service it is recommended to disassemble the
tool in a place where drainage for waste fluids is possible.

Hydraulic fluids, mud and grease are unsafe when touched by the skin. Always wear
gloves and safety goggles when disassembly the tool.

Remove all quick-disconnects, hoses, cylinders and manifold block and bleed of hydraulic
oil.

Clean the tool with a steam cleaner.

Remove the doors, latch, trigger valve, levers and discs and remove all bronze wear
bushings from the parts.

Carry of to proper place for final storage or destruction.

General Warnings;
¾ MAKE SURE A SAFE WORKING ENVIRONMENT IS PROVIDED WHEN FIELD
COMMISSIONING THE BX ELEVATOR.
¾ CLEANING REQUIREMENT OF THE SYSTEM BEFORE CONNECTING SYSTEM 21
PRODUCTS.
Clean, purge and pickle all hydraulic piping during and after installation and prior to
hooking up Varco System 21 equipment. The installation’s hydraulic pressure line from
the hydraulic power unit is to be looped to the installation’s hydraulic return line back to
the hydraulic power unit and hydraulic fluid is to be run through this loop for a period of 1
hour minimum, before hooking up pressure and return lines to system 21 equipment.
¾ REQUIRED (PLC input) FUNCTIONS IN DRILLERS CONSOLE AS SUPPLIED BY
DRILLERS CONSOLE MANUFACTERER.
Operating the BX Elevator.
On the driller’s console the following control functions need to be provided;
ƒ “Open” BX Elevator.
ƒ “Armed-to-Close” BX Elevator.
These functions can for instance be controlled with a two-position switch,
One position of the switch being the “Open” function, the other position
being “Armed-to-Close”.
Another option can be a spring-return push button. Releasing the push-button acts as
“Armed-to-Close” position for the BX elevator. To help prevent inadvertently opening
the Elevator it is recommended to program the PLC function so, that two pulses,
(“double-click”), from the BX control button are needed to generate a (timed, ~10secs
duration) open command to the BX control manifold. After timed function resets, BX
Elevator returns to “Armed-to-Close” state.
The (PLC outputs) Output function controls a solenoid operated Hydraulic valve
Situated on the Top-drive or inside the Hydraulic BX control cabinet situated in
the derrick at finger board level.
This valve is designated “DV1” and the line designation is “S2”
(see general HUK schematic #203447 in (BX) manual)

At the same time the BX elevator sends out a high pressure (equal to system pressure)
signal to the “Float-manifold located at / near the Pipe handler frame via line B5, to
port. “X” in the Float manifold.
This B5 “Float” Signal will activate valves inside the Float Manifold that will overrule
all Manual Rotate commands given by the Operator.
So after the last step of the “Closed-Signal” (and “Float”) test sequence is done,
i.e. “Elevator closed and latched”, the Rotator will start Floating the BX Elevator to it’s
normal near level position.

Notes:
1) Compatibility is based on API 8C contact radii unless link part # listed.
2) If a link part # is not listed, fit with the Elevator is to be confirmed.
3) In some cases special links are required for use on Top Drive
Solid Body Elevators to permit proper operation of Link Tilt.
4) In general, elevators fit one size larger and one size smaller nominal rated link.
However, fit should always be confirmed when combining links and elevators.

2.3 BX Rotators Controlled by Top drive Link Tilt
When you combine the controls for the Rotators with the Link Tilt, then there are 2
disadvantages then when you control the Rotators and Link Tilt separate.
1)
2)
Because you control the Rotators and the Link Tilt simultaneously, you will get
different resistance in your hydraulic system, this different resistance has
influence on the rotation of BX-Elevator and movement of the Links.
The Pipe Handler System must be more accurate to give the pipe to the Elevator
in the same position every time.

Mounting Plate Cabinet
The next items determine which Mounting Plate the customer will need for controlling
the equipment. The Elevator and the Power Slip each have their own Mounting Plate.

3.2 Electric System: Supply Voltage (03)
We need the supply voltage in order to determine the Solenoid Valve and the
Control Panel/Box (see chapter 6).
3.3 Air valve (04)
Power Slip
If the customer is going to use an air foot pedal to control the Power Slip then it is
necessary to mount an Air valve on the Control manifold.
If an air foot pedal is required to control the Power Slip, the following connection size
and working pressure is required:
Working pressure: minimum 84 PSI (6 Bar)
Connection size: O.D. 3/8” thread size JIC, 9/16-18 UNF
BX-Elevator
When the customer have an Air-operated Elevator and want to switch over to a
Hydraulic BX-Elevator. Than we use the existing control valve wich is already
installed for operating the Elevator. (see drawing: 203451)

Type of Hydraulic connection between Control Manifold
and Power Slip. (05)
There are 4 possible Options:
1. Hoses to Power Slip.
3H
Varco supplies all applicable Hydraulic Hoses with Aeroquip Quick Disconnect
Couplings. The hoses are 590” (ca. 15 meter) long.
The Hoses for the P and T from the power unit to the Control manifold must be
supplied by the customer.
2. Hard Tubing + hoses
HT
This Option is recommended by Varco because hard tubing is more rig proof than
hydraulic hoses.
When hardtubing is preferred, the installation has to be done by the original
manufacturer of the Rig. Varco supplies all applicable Hydraulic jumper Hoses with
Aeroquip Quick Disconnect Couplings.
The connection for P and T from the power unit to the Control manifold must be
supplied by the customer.
Hoses H.T. to PS are 100” (ca 2.5 meter) long.
Hoses Control Manifold to H.T. are 40” (ca 1 meter) long.
3. Only Q.D. Couplings
QD
This option is when the customer supplies all the hydraulic hoses. Than Varco has to
supply the Aeroquip Quick Disconnect Couplings, 1x hose assembly with ball valve.
4. Special Feature.
SF
- Specify the lengths of hoses according to customer specifications.
- Stainless Steel fittings: Yes
